Seriously upgrade your in-ear experience

Not convinced that in-ear headphones can deliver audiophile-grade, full-range sound? Let Denon's AH-C400 make a believer out of you. Small yet robust, these in-ears will blow away expectations for listeners used to punchless stock earbuds.

The AH-C400s use dual balanced armature drivers to generate stunning clarity across the musical spectrum, from deep bass to smooth mids and shimmering highs. A durable zinc die-cast housing protects the tiny drivers, isolating noise and reducing distortion so only your music comes through. The drivers are tuned for a flat, accurate response to deliver neutral sound that's free from the coloration introduced by many other headphones.

Customizable for ultimate comfort

Denon includes a wide assortment of eartips with the AH-C400, letting you find the perfect fit. This ensures not just comfort but a tight seal for optimum sound quality and noise reduction. The highly portable AH-C400 comes with a carrying case and features a Teflon-coated cable that reduces tangles. A convenient in-line remote with built-in microphone gives you iPhone®, iPod® and iPad® compatability for one-touch music playback and phone calls.

Includes the Denon Audio app

When listening to your mobile device, take advantage of the free Denon Audio app for Apple® and Android devices. This app features built-in graphic EQ, seamless music library integration and access to TuneIn® Radio's thousands of worldwide radio station streams.

Features

Drivers: The AH-C400 Music Maniac in-ear headphones feature Denon's
dual-balanced armature driver technology for studio-quality sound. These
balanced armature drivers are set in a zinc die-cast housing to effectively
isolate noise and enhance durability. The headphones are tuned to a flat EQ for
acoustic transparency.

Compatibility: The headphones feature an in-line Apple-compatible remote
control and microphone. These can control music operation
on compatible Apple devices and conduct phone calls or perform voice recognition
activities. The AH-C400s are compatible with iPod nano (4th gen or later), iPod
classic (120GB/160GB), iPod touch (2nd gen or later), iPod shuffle (3rd gen and
later), iPhone (3GS, 4, and 4S), and iPad. Audio is supported by all iPod
models, as well as virtually any device with a 3.5mm minijack output.

In-line Remote/Microphone: The integrated 3-button remote
and microphone, found on the left side cable, gives
you control of your iPod, iPhone, and iPad. The volume can be raised or lowered
incrementally with the two outer buttons. While listening to music, you can
control playback by pressing the center button for play/pause, next track,
previous track, fast forward, and fast reverse. Phone controls include
answer/end a call, switch to an incoming or on-hold call, put a call on hold, or
decline a call.

Headphone Cable: The headphones have a 54" Teflon-coated OFC
cable with a 3.5mm miniplug terminal. The clear, low-friction outer coating
helps keep the cable from getting tangled and reduces the chance you'll get
contact noise as you move. A 3.5mm-to-1/4" adapter is included for listening to
home components with a full-sized headphone output.

Comfortable Fit: The AH-C400 Music Maniac headphones are
designed for comfort and fit. After studying over 4000 pairs of ears, Denon's
engineers designed the earpieces to account for subtle differences in ear
placement, ear canal size, head size, and jaw depression. The headphones come
with multiple pairs of ear tips so you can choose the pair that gives you the
best fit and performance: 4 pairs of silicon ear tips (XS, S, M, L), 3 pairs of
double solid silicon ear tips (S, M, L), and a pair of Comply Foam ear tips.

Included Accessories: In addition to the ear tips, the
headphones come with a zippered, artificial leather case with a detachable
carabiner so you can hook the case onto a belt loop, a purse strap, or a
backpack.

Denon Club App: The Denon Club Smartphone Application for iPhone,
iPad, or Android is designed to enhance your listening experience. It includes a
real-time spectrum analyzer, and allows you to use any of 10 EQ presets, or
create, store, and share your own custom EQ curves. The app gives you access to
song lyrics, and create and store custom playlists. With the TuneIn Internet
Radio service, you can listen to any of over 50,000 internet radio stations.

Product reviews from the Crutchfield Labs

A lot to like

There is a lot to like with these headphones. First, they came with a good selection of eartips. I found a pair that fit comfortably in my ears and provided a good seal to keep out extraneous noises in the Crutchfield Labs.

Second, the headphones have a stylish, but practical design. The earbuds are almost minimalist, which meant I could barely feel them in my ears. The in-line controller is simple to use  volume up and down buttons, with a bigger control button in between. That button controls play and pause. Here's a tip: it also lets you skip forward or back through tracks. Two quick taps for skip forward, three quick taps for skip back.

Third, the sound is just what I want in a quality set of portable headphones. The bass full, the highs clean, and there was plenty of detail in the mid-range.
